59 git-cola uses QtPy, so you can choose between PyQt4, PyQt5, and
60 PySide by setting the `QT_API` environment variable to `pyqt4`, `pyqt5` or
61 `pyside` as desired. `qtpy` defaults to `pyqt5` and falls back to `pyqt4`
62 if `pyqt5` is not installed.
64 Any of the following Python Qt libraries must be installed:
66 * [PyQt4](https://www.riverbankcomputing.com/software/pyqt/download)
69 * [PyQt5](https://www.riverbankcomputing.com/software/pyqt/download5)
72 * [PySide](https://github.com/PySide/PySide)
75 Set `QT_API=pyqt4` in your environment if you have both
76 versions of PyQt installed and want to ensure that PyQt4 is used.
80 git-cola enables additional features when the following
81 Python modules are installed.
83 [send2trash](https://github.com/hsoft/send2trash) enables cross-platform
84 "Send to Trash" functionality.
86 # BREWING INSTRUCTIONS
90 You don't need to install git-cola to run it.
91 Running git-cola from its source tree is the easiest
92 way to try the latest version.
94 git clone git://github.com/git-cola/git-cola.git
99 Having git-cola's `bin/` directory in your path allows you to run
100 `git cola` like a regular built-in Git command:
102 # Replace "$PWD/bin" with the path to git-cola's bin/ directory
103 PATH="$PWD/bin":"$PATH"
109 The instructions below assume that you have git-cola present in your
110 `$PATH`. Replace "git cola" with "./bin/git-cola" as needed if you'd like to
111 just run it in-place.
115 * [HTML documentation](https://git-cola.readthedocs.io/en/latest/)
117 * [git-cola manual](share/doc/git-cola/git-cola.rst)
119 * [git-dag manual](share/doc/git-cola/git-dag.rst)
121 * [Keyboard shortcuts](https://git-cola.github.io/share/doc/git-cola/hotkeys.html)
123 * [Contributing guidelines](CONTRIBUTING.md)
127 Normally you can just do "make install" to install git-cola
128 in your `$HOME` directory (`$HOME/bin`, `$HOME/share`, etc).
129 If you want to do a global install you can do
131 make prefix=/usr install
133 The platform-specific installation methods below use the native
134 package manager. You should use one of these so that all of git-cola's
135 dependencies are installed.
137 Distutils is used by the `Makefile` via `setup.py` to install git-cola and
138 its launcher scripts. distutils replaces the `#!/usr/bin/env python` lines in
139 scripts with the full path to python at build time, which can be undesirable
140 when the runtime python is not the same as the build-time python. To disable
141 the replacement of the `#!/usr/bin/env python` lines, pass `USE_ENV_PYTHON=1`
146 Linux is it! Your distro has probably already packaged git-cola.
147 If not, please file a bug against your distribution ;-)
151 Available in the [AUR](https://aur.archlinux.org/packages/git-cola/).
167 zypper install git-cola
171 Available in [SlackBuilds.org](http://slackbuilds.org/result/?search=git-cola).
175 # install from official binary packages
176 pkg install -r FreeBSD devel/git-cola
178 cd /usr/ports/devel/git-cola && make clean install
182 The default version on 18.04 is older and is missing features and enhancements.
183 Use this [PPA](https://launchpad.net/~pavreh/+archive/ubuntu/git-cola)
184 maintained by @pavreh to get a newer version.
188 [Homebrew](https://brew.sh/) is the easiest way to install
189 git-cola's Qt4 and PyQt4 dependencies. We will use Homebrew to install
190 the git-cola recipe, but build our own .app bundle from source.
192 [Sphinx](http://sphinx-doc.org/latest/install.html) is used to build the
195 brew install sphinx-doc
196 brew install git-cola
198 Once brew has installed git-cola you can:
202 `git clone git://github.com/git-cola/git-cola.git && cd git-cola`
204 2. Build the git-cola.app application bundle
208 PYTHON=$(brew --prefix python3)/bin/python3 \
209 PYTHON_CONFIG=$(brew --prefix python3)/bin/python3-config \
210 SPHINXBUILD=$(brew --prefix sphinx-doc)/bin/sphinx-build \
214 3. Copy it to /Applications
216 `rm -fr /Applications/git-cola.app && cp -r git-cola.app /Applications`
218 Newer versions of Homebrew install their own `python3` installation and
219 provide the `PyQt5` modules for `python3` only. You have to use
220 `python3 ./bin/git-cola` when running from the source tree.
222 ### UPGRADING USING HOMEBREW
224 If you upgrade using `brew` then it is recommended that you re-install
225 git-cola's dependencies when upgrading. Re-installing ensures that the
226 Python modules provided by Homebrew will be properly set up.
228 This is required when upgrading to a modern (post-10.11 El Capitan) Mac OS X.
229 Homebrew now bundles its own Python3 installation instead of using the
230 system-provided default Python.
236 # uninstall git-cola and its dependencies
237 brew uninstall git-cola
241 # re-install git-cola and its dependencies
242 brew install git-cola
244 ## WINDOWS INSTALLATION
246 IMPORTANT If you have a 64-bit machine, install the 64-bit versions only.
247 Do not mix 32-bit and 64-bit versions.
249 Download and install the following:
251 * [Git for Windows](https://git-for-windows.github.io/)
253 * [Git Cola](https://github.com/git-cola/git-cola/releases)
255 Once these are installed you can run Git Cola from the Start menu.
257 See "WINDOWS (continued)" below for more details.
261 git cola ships with an interactive rebase editor called `git-cola-sequence-editor`.
262 `git-cola-sequence-editor` is used to reorder and choose commits when rebasing.
263 Start an interactive rebase through the "Rebase" menu, or through the
264 `git cola rebase` sub-command to use the `git-cola-sequence-editor`:
266 git cola rebase origin/main
268 git-cola-sequence-editor can be launched independently of git cola by telling
269 `git rebase` to use it as its editor through the `GIT_SEQUENCE_EDITOR`
270 enviironment variable:
272 env GIT_SEQUENCE_EDITOR="$PWD/bin/git-cola-sequence-editor" \
273 git rebase -i origin/main
277 The git-cola command exposes various sub-commands that allow you to quickly
278 launch tools that are available from within the git-cola interface.
279 For example, `./bin/git-cola find` launches the file finder,
280 and `./bin/git-cola grep` launches the grep tool.
282 See `git cola --help-commands` for the full list of commands.
284 $ git cola --help-commands
287 {cola,am,archive,branch,browse,config,
288 dag,diff,fetch,find,grep,merge,pull,push,
289 rebase,remote,search,stash,tag,version}
293 {cola,am,archive,branch,browse,config,
294 dag,diff,fetch,find,grep,merge,pull,push,
295 rebase,remote,search,stash,tag,version}
298 am apply patches using "git am"
299 archive save an archive
300 branch create a branch
301 browse browse repository
302 config edit configuration
309 pull pull remote branches
310 push push remote branches
311 rebase interactive rebase
313 search search commits
314 stash stash and unstash changes
316 version print the version
320 The following commands should be run during development:
325 # Run tests and longer-running pylint and flake8 checks
328 # Run tests against multiple python interpreters using tox
331 The test suite can be found in the [test](test) directory.
333 The tests are set up to run automatically when code is pushed using
334 [Travis CI](https://travis-ci.org/git-cola/git-cola).
335 Checkout the [Travis config file](.travis.yml) for more details.
337 Auto-format `po/*.po` files before committing when updating translations:
341 When submitting patches, consult the
342 [contributing guidelines](CONTRIBUTING.md).
346 For Linux/Unix-like environments with symlinks, an easy way to use the latest
347 `git cola` is to keep a clone of the repository and symlink it into your
348 `~/bin` directory. If `$HOME/bin` is not already in your `$PATH` you can
349 add these two lines to the bottom of your `~/.bashrc` to make the linked
352 PATH="$HOME/bin":"$PATH"
355 Then, install git-cola by linking it into your `~/bin`:
358 git clone git://github.com/git-cola/git-cola.git ~/src/git-cola
360 ln -s ../src/git-cola/bin/git-cola &&
361 ln -s ../src/git-cola/bin/git-dag)
363 You should then get the latest `git cola` in your shell.
368 Git Cola installs its modules into the default Python site-packages directory
369 (eg. `lib/python2.7/site-packages`), and in its own private `share/git-cola/lib`
370 area by default. The private modules are redundant and not needed when cola's modules
371 have been installed into the site-packages directory.
373 Git Cola will prefer its private modules when the `share/git-cola/lib` directory
374 exists, but they are not required to exist. This directory is optional, and can
375 be safely removed if the cola modules have been installed into site-pacakges
376 and are importable through the default `sys.path`.
378 To suppress the installation of the private (redundant) `share/git-cola/lib/cola`
379 package, specify `make NO_PRIVATE_LIBS=1 ...` when invoking `make`,
380 or export `GIT_COLA_NO_PRIVATE_LIBS=1` into the build enviornment.
382 make NO_PRIVATE_LIBS=1 ...
384 Git Cola installs a vendored copy of its QtPy dependency by default.
385 Git Cola provides a copy of the `qtpy` module in its private modules area
386 when installing Git Cola so that you are not required to install QtPy separately.
387 If you'd like to provide your own `qtpy` module, for example from the `python-qtpy`
388 Debian package, then specify `make NO_VENDOR_LIBS=1 ...` when invoking `make`,
389 or export `GIT_COLA_NO_VENDOR_LIBS=1` into the build environment.
391 make NO_VENDOR_LIBS=1 ...
393 Python3 users on debian will need to install `python3-distutils` in order
394 to run the Makefile's installation steps. `distutils` is a Python build
395 requirement, but not needed at runtime.
397 # WINDOWS (continued)
401 In order to develop Git Cola on Windows you will need to install
402 Python3 and pip. Install PyQt5 using `pip install PyQt5`
403 to make the PyQt5 bindings available to Python.
405 Once these are installed you can use `python.exe` to run
406 directly from the source tree. For example, from a Git Bash terminal:
408 /c/Python36/python.exe ./bin/git-cola
410 ## Multiple Python versions
412 If you have multiple versions of Python installed, the `contrib/win32/cola`
413 launcher script might choose the newer version instead of the python
414 that has PyQt installed. In order to resolve this, you can set the
415 `cola.pythonlocation` git configuration variable to tell cola where to
416 find python. For example:
418 git config --global cola.pythonlocation /c/Python36
420 ## BUILDING WINDOWS INSTALLERS
422 Windows installers are built using
424 * [Pynsist](https://pynsist.readthedocs.io/en/latest/).
426 * [NSIS](http://nsis.sourceforge.net/Main_Page) is also needed.
428 To build the installer using Pynsist run:
430 ./contrib/win32/run-pynsist.sh
432 This will generate an installer in `build/nsis/`.
434 ## WINDOWS HISTORY BROWSER CONFIGURATION UPGRADE
436 You may need to configure your history browser if you are upgrading from an
437 older version of Git Cola.
439 `gitk` was originally the default history browser, but `gitk` cannot be
440 launched as-is on Windows because `gitk` is a shell script.
442 If you are configured to use `gitk`, then change your configuration to
443 go through Git's `sh.exe` on Windows. Similarly, we must go through
444 `python.exe` if we want to use `git-dag`.
446 If you want to use gitk as your history browser open the
447 Preferences screen and change the history browser command to:
449 "C:/Program Files/Git/bin/sh.exe" --login -i C:/Git/bin/gitk
451 git-dag became the default history browser on Windows in `v2.3`, so new
452 users should not need to configure anything.
